Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

The Geritol Solution What is the basis for Martin’s premise that seeding the ocean with iron would help combat global warming? The idea of stimulating plankton growth with iron grew out of the fertile mind of the late John H. Martin‚ an oceanographer at Moss Landing. Martin sought originally to explain a long-standing mystery concerning barren waters in the Antarctic‚ subarctic‚ and equatorial Pacific Oceans. With the abundant concentrations of nutritious nitrate and phosphorus in

EXPERIMENT 2: SOLUTION PREPARATION AND STANDARDIZATION Submitted by Iris Olaso ______________________________________________________________________________ INTRODUCTION Generally‚ there are two ways in preparing a solution‚ one is by dissolving a weighed amount of solid in a required solvent and the other is by dilution of a concentrated solution into the desired concentration. In diluting concentrated solution‚ the concentration of the diluted solution can be determined by standardization

world today at our global civilization there are many problems that leap to our attention and everyone has a vested interest‚ one such example is food. Science has been tinkering with nature for the past one-hundred years trying to come up with solutions to help fight famine‚ and as a result‚ man made products have created ever more problems. The easiest way in which an individual or individuals can create change is to effect change in their local communities‚ so others can see an image of what the

Costing: A Tool to Aid Decision Making Solutions to Questions 7-1 Activity-based costing differs from traditional costing systems in a number of ways. In activity-based costing‚ nonmanufacturing as well as manufacturing costs may be assigned to products. And‚ some manufacturing costs—including the costs of idle capacity--may be excluded from product costs. An activity-based costing system typically includes a number of activity cost pools‚ each of which has its unique measure of activity

Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance

Around the world‚ forests are being logged for timber and paper pulp and cleared to grow mono-crops like palm oil and soy while they are deteriorating from the impacts of global warming. Deforestation is a major driver of global warming‚ responsible for up to 20 percent of global greenhouse gas emissions–more than all the cars‚ trucks‚ planes‚ boats and trains in the world combined. Deforestation doesn’t just threaten our climate‚ it threatens the livelihoods of 1.6 billion people that rely
